1. The quadrant of the life cycle of the fare where airlines process, audit, and collect sales from thousands of tickets.

2. (industry term) An airline IT application that examines past ticket sales in order to allocate revenue to appropriate carriers. Sales data is supplied to airlines by the GDSs and other sources via ATPCO's Sales Data Exchange, as well as internal airline systems. The tickets are then prorated based on existing agreements, and the results are sent to the ACH or IATA for settlement.

The practice of matching a passenger's specific demand for a product with an equivalent price. Developed by the airline industry in the 1970s, this practice demands highly complex and comprehensive data systems that allow businesses to vary price and availability to different market segments, and adjust these as necessary to capture or increase market share and revenue. In the airline industry, these actions are carried out by yield management in the case of inventory changes, and fare management in the case of pricing changes.

(Subcategory 103, International fares) Travel from the point of origin and return thereto which involves only one crossing of the Atlantic Ocean and only one crossing of the Pacific Ocean. Note that a single round-the-world fare component does not validate against Subcategories 102 or 103 (validation is only against Subcategory 104 to determine if End-on-End is required). See also combinations.

1. (Subcategory 102, US/CA fares) (data application) From point A to point B and return to point A on the same tariff, same carrier, same rule, and same round-trip fare class code. Note that if carriers wish to restrict the route of travel on the fares, then this can be done via the Routing Map and/or Category 4. See also combinations.

2. (Subcategory 102, International fares, excluding round-the-world fares) (data application) From point A to point B and return to point A using two fare components only, for which the applicable half-round-trip fare for each component, measured from point A, is the same for the routing traveled. Exception: If fares differ through class/season/day of week or carrier variation, it is still a round-trip. Note that after processing, if the results show a different HIP(Higher Intermediate Point) and/or a different mileage surcharge has been applied on fare component(s) in the pricing unit, then the above pricing solution would be considered a Circle Trip. See also combinations.
